German rod and part of crankshaft? ENGINE EXPERTS WELCOME!

[Dolpho]

Hello Flyboyj, I found a foto of a DB 605. The engine mounting is a swedish one. On Kurtls foto you can only see the cylinderbarrel ( 2 ), not the piston ( 7, 10 ). Number 9 are the pistonrings. Number 11 is the thread for fixing the cylinderbarrel into the cylinderbank. The piston is inside of the cylinderbarrel, so you can not see it

 

[FLYBOYJ]

Ah yes - OK - that explains it all - thanks for the photos - So we're looking at a 605?

@ Erich: Yes, we were talking about 25th July, 1944. Think that according Willi Reschke's book the JG 302 lost 4 Me109G's around that area. I'm pretty sure that I already located Uffz. Günter Richter's "Yellow 7". Erich do you think that there is any more information (except Reschke's book) about JG 302/301 available?
I believe that this second crashplace of obviously another Me 109 could fit to Uffz. Kemmerling. The book tells a name of a small town that this close to that place.
Do you have an idea if Reschke is still alive? I already have his adress. - Kurtl

HMM. Looking at some blueprints I have it looks like a DB601. What does the top of the piston look like?

this is from either a DB 601 or a 605. I would have to check the part numbers. The cylinder barrel has threads at the bottom to attach it to the crankcase. the next set of threads are where the barrel is screwed into the head and bank casting. The main cap has the cross bolt through the middle, with the four studs to hold it into the crankcase. the nuts are called notched nuts in the manual. there are splines on the outside for the socket to turn the nuts. the number of splines on the nuts are 54 and 58. I have rebuilt two of these engines and made the tooling for these nuts myself. the alum part at the end of the piston pin is the remains of the mushroom or pin retainer. it slid into the hole in the pin and had a large round end that just floated on the cylinder and kept the pin in place.

Found that piece on the same crashplace. What is it? "S" and "8832" are stamped into it. Here are the pictures:

Hello Kurtl,

look at the pictures at LBB « Luftwaffe Bullet Board » Forum zur deutschen Luftfahrtgeschichte , that were taken in our museum. They show DB605AS engine, but don´t know if it helps...8)

P.S. Willi Reschke is till alive. Look at the pictures at http://www.ww2aircraft.net/forum/album/showphoto.php?photo=14110&cat=602 , that were taken last year.

Hi Kurtl

I believe that part you found is a part of the fuel tank, a flange on top of the 400L main rubber tank in the Bf 109

To all engine specialists at this forum: From which engine is that part from? Any idea about the meaning of the numbers? I appreciate any information because I want to identify that aircraft. Thanks - Kurtl

Hi,
Another old thread but, I am going to come in here with some more detail that might be useful to other Daimler-Benz and Bf 109 specialists. The smashed crankshaft part with attached conrod, piston remains and liner, is from a DB605A, built by Niedersächsische Motorenwerke GmbH (NMW) "NiMo" in the spring of 1944. The large aluminium block with all the numbers on it is the centre main bearing cap, ie number 4, and the piston / liner / rod was with cylinder number 9 (the third from the front on the LHS). The engine number is 00203388 and would have been built in Spring 1944. The Sach-Nummer (part number) of the bearing cap is 9-601.104-067.22 and this is a DB601 derived part, as that casting was designed for the DB601E and continued in use on many DB605A engines.
This just illustrates some of the detail that is sometimes possible with DB601/3/5 engine parts.

Cheers

Hi ,
Another interesting detail is that I have data on the DB605 built just before this one on the production line. That engine was 00203387 and that was lost on 2.11.44 when fitted to Bf 109 G-14 W.Nr 462782.

How do you know ?

Hi Snautzer,

Just lucky that it is in a compilation of loss reports. The DB engine W.Nr are in batches with manufacture plant number codes, as well as the 3 letter Hersteller code on the Baumusterschild if you are lucky to have that. Numbers in close sequence are likely to have been on the production line in sequence. However, engines did get held-up or resequenced for various reasons during production, and dispatches to aircraft or store seem to often be quite a mixture. The engine batches would usually start with whole 000's but, all batches were not completed due to production changes or bombing etc. However, sequential numbers in blocks are the norm.
In Bf 109 aircraft, surviving engines were often replaced for workshop overhaul and the original aircraft / engine combination was lost.

Cheers

Heldrungen b. SO Reinsdorf Z Luft BF109 BF109G-14 462782 Gelb 11 100% loss Raimund Koch JG3 + 02.11.1944 htm Sta.Ka übungseinsatz

St. Wendel

German fighter pilot Raimund Koch was a member of 8./JG 3 and took part in the attacks on a formation of American 96 BG that had lost its way and attacked Ludwigshafen by error. He managed to save his life by bailing out. Just a few minutes before he had contributed to shooting down a B 17 commanded by pilot Notestein near Kaiserslautern.
Koch lost his life later that year, on 2nd November 1944 near the Esperstedt air base in Thuringia due to an error made by one of his comrades who rammed him at 400 m altitude. He had been credited with 47 shoot-downs and had been proposed for the award of the Knights Cross.

Without any question it is from a DB605

DB601 has a completely differently shaped main bearing cap (more like a triangle than a curve) and the DB603 main bearing cap has only 2 studs, not 4.
